REACTION OF α-CHLORO KETONES WITH ALLYLTRI-n-BUTYLTIN. CONTROL OF REACTION SITE BY THE VARIATION OF REACTION CONDITIONS

Reaction of α-chloro ketones with allyltri-n-butyltin proceeds to afford 4-butenyl ketones in the presence of azobisisobutyronitrile, while in the presence of catalytic amounts of tetrakis(triphenylphosphine)palladium allyl epoxides are obtained.
